My pump doesn’t work

  • Will breast pump work without valve
  • Will breast pump work without membrane
  • Why breast pump doesn’t work
  • I lost or broke a valve, can I get away without it? No, unfortunately. You will have to get another one because you won’t be able to get suction. Think about sucking on a straw, without having the other end blocked by your finger. It’s always good to have spares.
